WordPress powers over 40% of websites on the internet, making it the world’s most popular content management system (CMS). Its flexibility, ease of use, and massive ecosystem of themes and plugins make it an excellent choice for beginners and professionals alike.
However, no website platform is completely free from problems. Whether you run a personal blog, an online store, or a business website, you’re likely to encounter WordPress issues at some point. The good news is that most of these problems have straightforward solutions if you know where to look.
In this guide, we’ll cover the 10 most common WordPress issues, explain why they happen, and provide practical, step-by-step solutions to get your website back on track.
Why Do WordPress Issues Happen?
Most WordPress problems occur because of:
- Outdated plugins or themes
- Incompatible software updates
- Poor-quality hosting
- PHP version conflicts
- Incorrect file permissions
- Corrupted database files
- Excessive plugins
- Human errors during customization
Fortunately, nearly all of these problems can be fixed without rebuilding your website from scratch.
1. White Screen of Death (WSOD)
One of the most frustrating WordPress problems is the White Screen of Death, where your website displays nothing but a blank white page.
Common Causes
- Plugin conflicts
- Theme compatibility issues
- PHP memory exhaustion
- Fatal coding errors
How to Fix It
Disable Plugins
Access your website through your hosting File Manager or FTP.
Rename the plugins folder to something like: plugins_old
If your site loads again, one of the plugins is causing the issue.
Switch to Default Theme
Rename your current theme folder.
WordPress will automatically activate a default theme like Twenty Twenty-Six (if installed).
Increase PHP Memory Limit
Edit your wp-config.php file:
define(‘WP_MEMORY_LIMIT’, ‘256M’);
Enable Debug Mode
Add the following to wp-config.php:
define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
Check the debug log for the exact error.
2. Internal Server Error (500 Error)
The 500 Internal Server Error is one of the most common WordPress issues because it doesn’t clearly explain what’s wrong.
Possible Causes
- Corrupted .htaccess
- PHP timeout
- Plugin conflicts
- Server configuration problems
How to Fix It
- Rename the .htaccess file.
- Go to Settings → Permalinks and click Save Changes.
- Increase PHP memory.
- Disable plugins one by one.
- Contact your hosting provider if the issue persists.
3. Error Establishing a Database Connection
This error means WordPress cannot communicate with the MySQL database.
Common Reasons
- Incorrect database credentials
- Corrupted database
- Database server down
- Hosting issues
Solution
Open: wp-config.php
Verify:
- DB_NAME
- DB_USER
- DB_PASSWORD
- DB_HOST
If credentials are correct, repair the database.
Add: define(‘WP_ALLOW_REPAIR’, true);
Visit: yourdomain.com/wp-admin/maint/repair.php
Repair the database, then remove the above line from wp-config.php.
4. WordPress Stuck in Maintenance Mode
Sometimes after an update, WordPress gets stuck showing:
Briefly unavailable for scheduled maintenance.
Why It Happens
The update process was interrupted.
Fix
Delete the hidden file: .maintenance from your WordPress root directory.
Refresh your website.
Problem solved.
5. Login Page Keeps Refreshing
You enter the correct username and password but are redirected back to the login page.
Causes
- Corrupted cookies
- Incorrect site URL
- Plugin conflicts
Fix
Clear:
- Browser cache
- Cookies
Check these values in Settings → General:
- WordPress Address (URL)
- Site Address (URL)
They should match your website URL.
If locked out, update them in wp-config.php.
6. WordPress Website Running Slow
Website speed directly impacts SEO, user experience, and conversions.
Reasons
- Cheap hosting
- Too many plugins
- Large images
- No caching
- Heavy themes
How to Improve Speed
- Install a caching plugin.
- Compress images.
- Enable GZIP compression.
- Use a CDN.
- Remove unused plugins.
- Update PHP to the latest supported version.
- Optimize the database regularly.
7. Images Not Uploading
Sometimes WordPress displays:
HTTP Error
or refuses image uploads.
Possible Causes
- Incorrect file permissions
- Low PHP memory
- Plugin conflicts
Solution
Set folder permissions: 755
Set file permissions: 644
Increase:
- upload_max_filesize
- post_max_size
- memory_limit
Disable image optimization plugins temporarily.
8. WordPress Keeps Logging You Out
You log in successfully but are immediately logged out after a few minutes.
Causes
- URL mismatch
- Browser cookies
- Cache issues
Fix
Ensure these URLs are identical: https://yourdomain.com
for both:
- WordPress URL
- Site URL
Clear browser cookies and website cache.
9. Plugin or Theme Update Failed
Sometimes updates fail with messages like:
- Update failed
- Installation failed
- Could not create directory
Common Causes
- Low disk space
- File permission issues
- Hosting restrictions
Solution
Check:
- Available hosting storage
- File permissions
- PHP version compatibility
Update manually using FTP if automatic updates fail.
10. WordPress Not Sending Emails
Many WordPress websites fail to send:
- Contact form notifications
- Password reset emails
- WooCommerce order emails
Why It Happens
Most hosting providers don’t configure PHP mail properly.
Best Fix
Instead of using PHP mail, configure SMTP.
Popular SMTP plugins include:
- WP Mail SMTP
- FluentSMTP
- Easy WP SMTP
Use email providers like:
- Gmail SMTP
- Outlook SMTP
- SendGrid
- Mailgun
- Amazon SES
SMTP significantly improves email delivery.
